RCD being used as a main switch

[Des 56]

Not aware that one RCD has ever been the norm?

Then you never lived in my part of the world to see in the early seventies
If there happened to be any sort of circuit breaker it would have been a voltage operated elcb
The Rcd that replaced these were fitted to almost every household electrical system that existed in that location

Quite.
Loads of houses on a TT supply with one upfront ELCB or RCD.

If total loss of power is regarded as a significant safety issue, then emergency lighting or an automatic-start backup generator should be installed to cater for power cuts. Or a UPS fitted to specific items of essential equipment.

Yep: Front end ELCB or RCD covering the whole installation was the norm down here too, still lots of them in daily use.

OP, are you referring to a domestic installation?
On a distribution system, many installations use a RCD as main isolation switch.

Err how can a bedside be used and how can the sockets not be affected ?? The point is the rcd is the main isolator switch and also controls all circuits !

Talking about a dual rcd db and that you can have up lights on one rcd and up sockets on the other thus if rcd protecting up lights trips then at least a bedside lamp can be used on the upstairs sockets so there can be some light.
Read it again!

I'm lost!
I was referring to a dual rcd consumer unit I would have to go and read through the entire thread again to see what context I brought this up with.
Hope you commented on lack of circuit identification tho

Yeah good idea - re read the thread .
The convo wasn't about a dual rcd .

Like this thread, I already did "move on"

Be relevant then . Commenting on Australia in a geography exam , when the
Question is about China will get you marked down lol

I've never ever used RCD's in a domestic installation. Split load 2 RCD boards are not for me! 100A main breaker/isolator with RCBO's is the only way. AMEN

Double pole

Only true Double Pole RCBO's not those silly things with fly leads.

Not bad.. more than 3 years old and still an active thread.

I some times feel as though I have been resurrected as well, especially first thing in the morning.

Amen to that. My preferred method since 1998.With the 63 amp main switch in place of the 100 amp (don't have them yet)
